It is supported by a MPPT algorithm and can deliver “up to 98-percent efficient power extraction in applications such as solar battery charge controllers, distributed MPPT and micro-inverters,” said NXP.
The MPT612 can be configured for a variety of DC solar charge controller applications using MPPT, and is also “ideal for non-storage-based electric motors for water pumps and fans”.
“Compared to traditional PWM controllers, MPPT controllers can extract up to 30-percent more power from a solar PV panel,” said Jan Willem Vogel, senior director, industrial applications marketing, NXP Semiconductors. “Our expertise in High Performance Mixed Signal technologies has enabled us to develop a unique MPPT IC and algorithm that enables PV integrators to further improve efficiency across a wide range of solar cell and fuel cell applications.”
The MPT612 is based on a low-power, 32-bit ARM7TDMI-Sâ„¢ processor, which supports I2C, UART, SPI and SSP interfaces. It also features hardware functions needed in PV applications and can send an output signal to control external switching. It offers up to 15 KB of flash memory and three levels of flash Code Read Protection (CRP).
